Description
FIELD OF THE INVENTION
The present invention relates generally to systems and devices
designed to test and/or charge batteries. The present invention
also relates generally to methods for testing and/or charging
batteries.
BACKGROUND OF THE INVENTION
When the owner of a vehicle brings an allegedly defective vehicular
battery to a mechanic shop or automotive repair center, a mechanic
will typically first ensure that the battery is indeed defective.
This is done to ensure that the problem is not somewhere else in
the vehicle.
In order to conduct a diagnostic test on the battery, the mechanic
uses either an independent tester and manual charger or a system
that is an integrated combination of a battery testing device and a
battery charging device. According to this currently available
system, if the battery is diagnosed as having too low of a charge
by the battery testing device, the battery charging device will
commence charging the battery. Since the charging operation may
take one hour, two hours or more, a low or discharged battery will
prevent the mechanic from using any part of the system on another
battery.
In view of the above, mechanic shops and automotive repair centers
that regularly encounter multiple customers requesting battery
diagnoses and/or charges at substantially the same time typically
invest in multiple integrated battery testing and charging systems.
Unfortunately, this leads to inefficiency since the battery testing
procedure typically takes on the order of a minute or less to
complete while, as mentioned above, the charging procedure may take
hours.
SUMMARY OF THE INVENTION
At least in view of the above, it would be desirable to provide
novel battery testing and charging systems wherein a single battery
testing device could be used in conjunction with multiple battery
charging devices. It would also be desirable to provide novel
methods for testing and charging a batteries that allow for the use
of a single battery testing device in conjunction with multiple
battery charging devices.
The foregoing needs are met, to a great extent, by one or more
embodiments of the present invention. According to one such
embodiment, a battery testing and charging system is provided. The
system includes a battery testing device and a battery charging
device. The battery testing device includes a processor configured
to perform a test on a battery when the battery is connected to the
battery testing device. Once the test (or at least a portion of the
test) is concluded, the battery testing device also includes a
transmitter that is configured to transmit test data collected
during the test. The battery charging device is separable from the
battery testing device and includes a receiver configured to
receive the test data (e.g., the appropriate charging data) from
the battery testing device. The battery charging device also
includes charging circuitry having a particular configuration. More
specifically, the charging circuitry is configured such that, when
the battery charging device is connected to the battery, the
charging circuitry charges the battery based upon the test
data.
In accordance with another embodiment of the present invention, a
method of testing and charging a battery is provided. The method
includes performing a test on a battery using a battery testing
device when the battery is connected to the battery testing device.
The method also includes transmitting from the battery testing
device test data collected during the test. The method further
includes receiving the test data in a battery charging device that
is separable from the battery testing device. In addition, the
method also includes charging the battery based upon the test data
when the battery is connected to the battery charging device.
In accordance with yet another embodiment of the present invention,
another battery testing and charging system is provided. The system
includes means for testing a battery when the battery is connected
to the means for testing. The system also includes means for
charging the battery when the battery is connected to the means for
charging, wherein the means for charging is separable from the
means for testing. The system further includes means for
transmitting test data collected by the means for testing during
the test to the means for charging, wherein the means for charging
is configured to receive the test data and to charge the battery
based upon the test data.
There has thus been outlined, rather broadly, certain embodiments
of the invention in order that the detailed description thereof
herein may be better understood, and in order that the present
contribution to the art may be better appreciated. There are, of
course, additional embodiments of the invention that will be
described below and which will form the subject matter of the
claims appended hereto.
In this respect, before explaining at least one embodiment of the
invention in detail, it is to be understood that the invention is
not limited in its application to the details of construction and
to the arrangements of the components set forth in the following

DETAILED DESCRIPTION
The invention will now be described with reference to the drawing
figures, in which like reference numerals refer to like parts
throughout. FIG. 1 is a perspective view of a battery testing and
charging system 10 according to an embodiment of the present
invention. As illustrated in FIG. 1, the system 10 includes a
battery testing device 12 and a battery charging device 14.
FIG. 2 is a schematic diagram of components included within a
battery testing device and battery charging device according to an
embodiment of the present invention. As illustrated in FIG. 2, the
battery testing device 12 includes a processor 16 and a transmitter
18. As also illustrated in FIG. 2, the battery charging device 14
includes a receiver 20 and charging circuitry 22. (It should be
noted that, according to certain embodiments of the present
invention, the transmitter 18 and/or the receiver 20 may be
replaced by a transceiver.)
According to certain embodiments of the present invention, the
processor 16 is configured to perform a test on a battery (not
illustrated) when the battery is connected to the battery testing
device 12. In some such embodiments, the transmitter 18 is
configured to transmit test data collected during the test
performed by the processor 16. Within the battery charging device
14, the receiver 20 is configured to receive the test data from the
transmitter 18 within the data testing device 12. Then, the
charging circuitry 22 is configured to charge the battery based
upon the test data when the battery is connected to the battery
charging device 14.
As illustrated in FIG. 1, according to certain embodiments of the
present invention, the battery testing device 12, includes an
operator interface 24. The operator interface 24 is configured to
receive input from an operator of the battery testing device 12
(e.g., a mechanic) about at least one parameter of the battery. In
FIG. 1, the operator interface 24 includes a plurality of buttons
and knobs and a display screen. However, other methods of receiving
input from an operator are also within the scope of the present
invention.
Once the input is received from the operator, the battery testing
device 12 is configured such that the input may be transmitted from
the battery testing device 12 to the battery charging device 14. In
such instances, the charging circuitry 22 is typically further
configured to charge the battery based upon the input as well as
the test data when the battery is connected to the battery charging
device 14.
The above-discussed the input may be, for example, the rated
voltage of the battery, the size of the battery, the type of
battery, etc. The test data may be, for example, the battery charge
level, the battery capacity, the time (i.e., length) of charge
needed to obtain a desired level of charge (i.e., how long the
battery should remain in the battery charging device 14), etc.
According to certain embodiments of the present invention, the
processor 16 is configured to perform tests on more than just
battery. For example, the processor 16 may, in some instances, the
configured to perform tests on an electrical system of the vehicle
from which the battery was removed when put into the battery
charging device 14.
The battery testing and charging system 10 illustrated in FIG. 1
illustrates that, according to certain embodiments of the present
invention, the battery testing device 12 is configured to be docked
in a port 26 of the battery charging device 14. According to such
embodiments, there is a direct link between the transmitter 18 and
the receiver 20 that allows for communication between these two
components.
According to certain embodiments of the present invention, docking
the battery testing device 12 in the port 26 does more than
facilitate and/or enable communication between the battery testing
device 12 and the battery charging device 14. More specifically,
while docked, the battery testing device 12 according to these
embodiments also gets charged by the battery charging device
14.
FIG. 3 is a schematic diagram of a battery testing and charging
system 10' according to another embodiment of the present
invention. The system 10' is illustrated in FIG. 3 while in
operation and includes not only the above-discussed battery testing
device 12 and battery charging device 14 but also illustrates a
second battery charging device 14', an additional network component
15, a central database 28, a network 30 and a printer 32. FIG. 3
also clearly illustrates that the battery testing device 12 is
separable from each of the battery charging devices 14, 14'. (One
of skill in the art will appreciate, upon reviewing FIG. 3 that the
battery charging devices 14, 14' are models in which the battery
testing device 12 may be docked and will further appreciate that
the second battery charging device 14' can communicate wirelessly
not only with the battery testing device 12 but also with any other
component illustrated in FIG. 3).
The additional network component 15 illustrated in FIG. 3 takes the
form of a rotating electrical tester. As such, alternators and/or
starters may be tested therein. However, other devices are also
within the scope of the present invention, including devices
configured to communicate wirelessly with other components.
In operation, the battery testing device 12 may communicate with
either of the battery charging devices 14, 14' or, according to
certain embodiments of the present invention, with both. More
specifically, the transmitter 18 in the battery testing device 12
illustrated in FIG. 3 communicates wirelessly with either or both
of the receivers (e.g. receiver 20 in battery charging device 14)
in the battery charging devices 14, 14'. Also, in addition to being
docked in port 26 or communicating wirelessly, the above-mentioned
transmitters and receivers may communicate utilizing one or more
inter-connecting cables as illustrated in FIG. 2 with transmitter
18, receiver 20 and cable 33.
According to certain embodiments of the present invention, the
central database 28 is configured to store test data and/or
operator input for a plurality of battery tests. Although
illustrated as a separate component in FIG. 3, the central database
28 may also be located in either a battery testing device or a
battery charging device. Once enough data has been accumulated in
the central database 28, a variety of statistical analyses may be
performed to evaluate battery quality, reliability of the tester,
efficiency of a charger, etc.
The network 30 illustrated in FIG. 3 maybe, for example, a local
area network or the Internet. Although FIG. 3 illustrates that the
battery testing device 12 communicates only with the battery
charging devices 14, 14', that the battery charging devices 14, 14'
communicate only with the central database 28 and the battery
testing device 12, and that the network 30 communicates only with
the central database 28 and the printer 32, other lines of
communication between the components illustrated in FIG. 3 are also
within scope of the present invention. It should also be noted that
software (e.g., updates for the battery testing device 12, the
battery charging devices 14, 14', the central database 28 and/or
the printer 32 maybe easily disseminated throughout the battery
testing and charging system 10' using the lines of communication
illustrated in FIG. 3. Also, a mechanic has the opportunity to
remotely turn off any of the battery charging devices 14, 14'
either during or after a battery charge.
The printer 32 illustrated in FIG. 3 may be any device capable of
generating documents (e.g., reports, lists of data, etc.). In
addition, other components may be included in the battery testing
and charging system 10'. For example, video monitors, remote
operator interfaces and/or signal alarms indicating the completion
of a charge may be included.
FIG. 4 is a flowchart illustrating the steps a method 34 of testing
and charging a battery according to an embodiment of the present
invention. The method specifies, in step 36 thereof, that a test
may be performed on a battery using a battery testing device (e.g.,
device 12) when the battery is connected to the battery testing
device. Although automotive batteries may become the primary
beneficiaries of the systems and methods disclosed herein, it
should be noted that supporting batteries included in motorcycles,
industrial equipment, farm equipment, marine vehicles, etc. are
also within the scope of the present invention.
Step 38 of method 34 specifies transmitting from the battery
testing device test data was collected during the test. As will be
appreciated by one of skill in the art upon practicing the present
invention, the test data maybe transmitted on an intermittent basis
or all at once at the conclusion of one or more tests. As will also
be appreciated by one of skill in the art upon practicing the
present invention, the transmission may occur while the battery
testing device is docked in a port of a battery charging device,
while connected to the battery testing device via a cable,
wirelessly, etc.
Step 40 then specifies receiving the test data in a battery
charging device (e.g., battery charging device 14, 14') that is
separable from the battery testing device. As specified in step 42,
once the data has been transferred, the charging of the battery may
occur based upon the test data when the battery is connected to the
battery charging device. According to certain embodiments of the
present invention, the above-discussed input received from an
operator and/or other parameters may be use by the battery charging
device as well.
Step 44 specifies periodically synchronizing the battery testing
devices and the battery charging devices. One benefit of such
synchronization is the resultant increase in data reliability.
Synchronization on a periodic basis may also be performed between
other system components.
According to step 46, the test data is forwarded to a central
database (e.g., database 28). Once in the database, the data maybe
manipulated in any manner that would prove useful to owner or
operator of a system according to the present invention. For
example, statistical analysis may be performed.
Step 48 specifies docking the battery testing device in a port of
the battery charging device. According to step 50, the
above-mentioned transmitting and receiving steps may be performed
while the battery testing device is docked in the battery charging
device. According to step 52, the battery testing device may also
be charged while the battery testing device is docked in the
battery charging device. As an alternative, other methods may be
used to charge the battery testing device. For example, batteries
may be swapped out or the battery testing device may be plugged
into an outlet.
In addition to the above-discussed testing of batteries, according
to step 54, the battery testing device may also be utilized to
perform one or more additional tests on one or more electrical
systems of a vehicle. In other words, according to certain
embodiments of the present invention, the battery testing device is
configured to test vehicular components other than batteries.
FIG. 5 is a flowchart 56 illustrating the steps of a method of
updating software according to an embodiment of the present
invention. As specified in step 58, a battery testing and charging
system that includes at least one battery testing device and at
least one battery charging device is selected. For example, the
system 10' discussed above may be selected during step 58. Then,
according to step 60, software is wirelessly updated on at least
one of the battery testing devices and/or the battery charging
devices. In addition, such updates may be performed using cables
and/or other means of connectivity. Also, using the method whose
steps are illustrated in FIG. 5, updates may be made to the
software of other components in a battery testing and charging
system.
The many features and advantages of the invention are apparent from
the detailed specification, and thus, it is intended by the
appended claims to cover all such features and advantages of the
invention which fall within the true spirit and scope of the
invention. Further, since numerous modifications and variations
will readily occur to those skilled in the art, it is not desired
to limit the invention to the exact construction and operation
illustrated and described, and accordingly, all suitable
modifications and equivalents may be resorted to, falling within
the scope of the invention.
